Love The Necks. I saw them supporting Swans a few years back. They were brilliant.

I don't often put myself in a position where I recommend music to people. However, if I were to recommend Autechre to someone, I would probably go for Oversteps or Exai. I feel like these albums strike a good balance between having something familiar for newcomers to grab onto, while also still being pretty 'out there'. It's not exactly going to be easy for someone who hasn't heard anything like it before, but it's less jarring than their recent output (note: that's a relative statement!), yet more unique than their earliest stuff (which I still love).
Although, if I really wanted to showcase Autechre to someone, I might even just make them a playlist of a few choice tracks to start with.
In addition to this, you can customise your own key bindings for a ridiculous amount of actions and even chains of actions. You can potentially perform fairly complex tasks with a single key. With enough repition you can quickly perform almost any process you like without thinking too much about it. The tricky part, at first, is figuring out what name the thing you're thinking of is given in the Reaper action list.
FWIW from a Linux newbie, I ended up going for a gaming laptop. I was originally going for a Thinkpad, but honestly, after doing some reading on how Linux runs on various laptops, everything seemed to have people stating they had no real issues and people stating they had lots.
So I took a risk and got myself a Gigabyte G5. Three storage slots (good for separating samples or recording, virtual instruments etc.), decent enough cpu, up to 64gb ram (nice to know the option is there just in case), and gpu that will let me edit some stuff in Resolve.
The CPU (i5-11400H) has very similar specs to my desktop PC, which is about 4 years old now, but has never once broken a sweat with many, many tracks of audio, multiple instances of Serum and other softsynth, reverbs and delays etc, and Addictive Drums 2. So I don't think you need a high end cpu, but something with a few cores.
For video editing, I seem to remember that will depend a lot on your software of choice, and how much you're pushing it. For example, I use Resolve, which draws a lot from gpu, whereas other software might need better cpu specs.
I haven't used Reaper, my DAW of chioce on it yet, but Pd and SuperCollider are working perfectly.
I'm not an expert though so take all of this for what it's worth!
